Norma Plummer AM said she was deeply honoured by the recognition.
"This is a tremendous honour and one I certainly never expected. The Constellation Cup has created so many memorable moments, and to have our names associated with an award that celebrates its legacy is incredibly special," she said.
"Ruth and I shared some remarkable on court battles over the years, but there was always enormous respect between us. To have our names linked through this award is something I am truly proud of."
Netball Australia Chair Liz Ellis AO said the medal was an appropriate tribute to two of the sport's most influential figures.
"The Constellation Cup is one of the most fiercely contested rivalries in world sport, and it is fitting that the outstanding player across the series is recognised with an award that recognises the integral role these two women have played as both players and coaches.
"Norma Plummer and Ruth Aitken had one of the greatest coaching rivalries our game has seen, and both have left an indelible mark on netball. As someone who played during this time, I am grateful that I got to see first-hand the dedication, passion and mastery of both women.
"The Plummer-Aitken Medal is a tribute to their legacy and will inspire future generations of players who aspire to excel on the Constellation Cup stage."
Netball New Zealand Board Chair Alastair Carruthers CNZM said the award reflects the very spirit of the Constellation Cup.
"Dame Ruth Aitken and Norma Plummer are true icons of our game. As players, coaches and leaders, they inspired generations on both sides of the Tasman and helped define an era of international netball.
"What makes this award so special is that it brings together two fierce competitors who pushed each other relentlessly yet always carried a deep respect for one another and for the game itself.
"That spirit sits at the heart of the Constellation Cup and makes the Plummer-Aitken Medal a fitting addition to a rivalry that has helped define international netball for generations."
